4 Claims."

This invention relates to air conditioning and ventilating means for brooders, and it consists in the constructions, arrangements and combinations herein described and claimed.

It isan object of the invention to provide an apparatus which will effectively and economically force foul air and high humidity out of the brooder space and insure a positive supply of fresh air to the fowls under the brooder.

It is a still further object of the invention to provide a construction which will function to uniformly distribute fresh air throughout the brooder.

It is also an object of the invention to provide an air conditioner which may be readily installed in old as well as new brooders, regardless of the mode of heating means employed.

Additional objects, advantages and features of invention will be apparent from the following description considered in conjunction with the accompanying drawing forming a part of this application, wherein Figure 1 is an elevation of my invention, partly in section.

Figure 2 is a side elevation of the air regulating means, the parts being shown in separate position.

Figure 3 is a cross section on the line 3-3 ,of Fig. 1.

There is illustrated in Figure 1, the upper'portion III of a brooder which may be of any conventional construction, embodying a vent I, which in the present instance is defined by an annular collar l2.

A tube I3, which may be of any suitable length is frictionally or otherwise fitted within the vent H, and upon the lower end of the tube which is disposed within the brooder there is secured an annular bafiie plate It. ,The plate I is substantially dish-shaped, the annular flange l5 being presented in an upwardly direction, so that air issuing from the tube l3 will be diverted upward- I ly and toward the sides of the brooder; thereby insuring a thorough circulation of air through all parts of the brooder, yet preventing a direct blast of air upon fowl housed within the brooder.

Various means may be employed for securing the baffle plate to the tube, and in the present construction, there is shown a clamp collar l6 of a size to loosely receive the tube 3, and from the collar l6 downwardly extended legs I! are provided, each leg terminating in a foot portion l8 which flatly abut the plate H. The plate may be secured to the foot portions in any approved manner, as by riveting, welding, soldering, 'or otherwise.

The ring I6 is preferably ofan expansible nature, the right angularly disposed ears IQ of which are secured by a clamping screw 20.

From the construction described it will be obvious that the plate I may be adjusted toward or away from the end of the tube, by merely loosening the screw 20 and moving the collar It to the desired position upon the tube l3, and such adjustment of the plate will vary the deflection of the air currents issuing from the tube.

The upper end of the tube, which is disposed outward of the brooder, terminates in an annular flange 2| upon which there is secured a. drum 22. The drum 22 has an open upper end and at suitable points in the side wall thereof, a apertures 23 are formed, which function to admit air into the tube l3 as will be more fully explained hereinafter.

An electric motor 24 is mounted upon the flange 2| by means of brackets 25, the shaft 26 of which is centrally disposed within the tube l3, and is of a length to extend a substantial distance thereinto, and has fixed thereto a fan 21, which is of a size to freely revolve within the tube l3.

plurality of 15 25 A cover 28 is provided for the drum 22, and

comprises an annular wall 29 of a diameter to telescopically receive the wall defining the drum 22, the flange 2| which extends slightly beyond the drum serving as a supporting means for the 30 cover by virtue of the contacting relationbetween the flange 2| and the lower edge of the cover. As shown, the roof portion 30 may have a conical shape.

The annular wall 29 has formed therein a plu- 35 rality of apertures 3|, so positioned as to align with the apertures 23. The cover 28 is revoluble within the drum, and therefore the degreeof opening between the apertures 23-3| may be varied, and as shown in Figure 1, the cover has been rotated to such an extent that a proximately but one-third of the openings 3| are uncovered. It will be seen therefore that the amount of air admitted into the tube l3 may be readily regulated.

. Electromotive force may be supplied to the motor 24 through the leads 32 connected to a line 33 having an attaching plug 34 for insertion in the usual house line, not shown.

In order that the air discharged into the 50 31 may be employed for housing the splices of the leads to the motor and heater. The heater coil 35 is preferably mounted in spaced relation to the plate IQ, in order to permit ready circulation of air, and in the present instance, this is accomplished by insulated studs 38. While a single heating coil 35 is shown, it will be obvious that a number of coils may be employed, and that the heating coil and motor may be so connected as to function simultaneously or separately, as desired.

The operation The operation will be readily understood from the following description.

Upon insertion of the plug 34 in a suitable socket of a power line, the motor 24 will be energized, as will the heating coil 35. with energization of the motor, the fan 21 will be caused to rotate, and by such rotation will force air downwardly through the tube l3, the air being deflected by the baiile plate I, into and across the heating coil 35, thereby suitably tempering the air. The air which is drawn into and discharged through the lower end of the tube must enter the tube by way of the drum 22 and cover 29, through the apertures 23--3l. The amount of air admitted to the drum is controlled by the degree'of setting of the apertures 3| with respect to the apertures 23, and this setting is accomplished by rotation of the cover 28. 8

The cover 28 is also removable, permitting ready access to the motor forrepair or other attention." a i From the foregoin'g,.it will be apparent that I have provided an air conditioning means em bodying a forced circulation of air within a brooder, which is of extremely simple construction and requiring minimum of attention in use.

If for any reason, the fan should cease to function, the tube and drum will thenact as an out- .let for the air within the brooder, in which event the air will travel upwardly through the tube and outwardly through the apertures 23-3l to the atmosphere.

While I have shown and described a preferred embodiment of the invention, I am aware that various changes in construction may be made,

and I reserve as my own, allsuch modificationsv as fairly fall within the scope of the appended claims.

I claim:-

1. In a brooder, a tube having a horizontal flange and an apertured drum, a cover member for seating engagement with the horizontal flange and having an annular flange telescopically and rotatably positioned about the drum, said flange having apertures adapted to register with the apertures of the drum defining air inlet openings, a defiebt'or plate at the discharge end of the tube, fan means within the tube for drawing air thereinto, and heating means carried by the deflector plate.

2. In a brooder, a tube having a horizontal flange and an apertured drum, a cover member having an annular flange for seating engagement with the horizontal flange and telescopically and rotatably positioned about the drum, said flange having apertures adapted to register with the apertures of the drum defining air inlet openings, a deflector plate at the discharge end of the tube, and air heating means carried by the deflector plate.

3.
